INTERNAL-COMBUSTION ENGINE.

Application filed April 4, 1928. Serial No. 267,317.

intake and exhaust thereby eliminating the usual valves for such purposes. 1 A further object of the invention is the provision of an internal combustion engine having a plurality of cylinders which are 20 oscillated by a revolving crank shaft, the

cylinders having a pivotal support intermediate the ends thereof, a lever arm being connected to the cylinder and embracing the crank shaft with a yoke connected to a piston and slidable in the arm, the yoke carry: ing the bearings which receives a crank of the shaft, the construction being such that the arm acts as a lever of a length which will place the point of application to the inertia load whenthe force applied to this load will be exerted to prevent undesirable stresses or wear on the assembled unit.

A still further object of the invention is the provision of an internal combustion en gine having a U-shaped lever arm connected to a cylinderin which is reciprocated a U- shaped member connected to a piston, a ball bearing being carried the U-shaped member with a block retaining the bearing in position, a rod connected. to the piston in turn acting as a clamp for forcing the block in snug contact with the bearing.

This invention will be best understood from aconsideration of the following detailed description; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications. which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a horizontal, longitudinal section of an engine constructed according to the principle of my invention,

of the burnt gases from the cylinder.

Figure 2 is a side yieW of the engine partly in section, the cylinder being alined,

Figure 3 is a side view of the engine partly in section showing the cylinders at an angle to each.

Referring more particularly to the drawings 10 designates a supporting frame consisting of side plates 11 and 12 connected together at their ends by bars 14: to which are bolted heads 18.

The heads and plates are provided respectively with sections 15 and 16 of a bearing in which is mounted a ball bearing 17. Trunnions 18 are received by the bearing 17 and support an oscillating cylinder 19 or The opposite ends of the frame are provided with sockets 21 in which are fitted, semi-circular enlargements 22 and 23 which are formed complementarily to the sockets. The enlargements have a close fit with the walls of the sockets to prevent the leakage of fluid past the same as will be presently explained. v

The enlargement 22 is formed integrally with the cylinder and has a plurality of intake ports 30 adapted to aline with similarly shaped ports 31 formed in one portion of the socket 21. The ports 31 are in direct communication with a source of compressed air for supplying the cylinder with fluid to support combustion. The ports 30 are con.- trolled by a piston 32 and by the oscillation of the cylinder whichcauses the enlargement to cover the ports 31 at times.

Diametrically opposite the ports 30 are ports 40 formed in the enlargement 2 3, which is likewise cast integrally with the cylinder. Ports 4:1 in the opposite portion of the. socket 21 are adapted to be alined with the ports 40 periodically, and such alinement is controlled by the oscillation of the cylinder and the reciprocation of the piston cooperates with the oscillating cylinder for determining the time of the exhaustion The gases are conducted away from the cylinder by the usual exhaust pipe (not shown).

A deflecting plate 42 J's-mounted oneach piston at the intake side of the cylinder, whereby a more thorough scavenging of the cylinders will be had when the air is admitted through the intake ports 30 and 31.

It will be appreciated that both cylinders 19 and 20, together with the construction of the enlargements and intake and exhaust ports, are identical in. construction.

Each piston has a Ushaped arm or yoke rigidly or integrally connected thereto. This yoke has a curved bight 51, which carries a roller bearing 52 embracing a crank pin 53. A block 54 is mounted in the U-shaped member 50, and has an arcuately shaped shoe 55 forced into engagement with the bearing 52 for retaining the bearing in position. A red 56 has one end seated in a socket 57 in the block 5d, and the other end screwed into the piston A look nut 58 threaded onto the rod 56 maintains the adjustment of said red when it has been turned to force the block 54 into rigid engagement with the bearing 52. j

A ring 60 has external threads 61, which are screwed into the inner portion of the enlargements 22 and 23. A U-shaped lever or arm 62 is formed integrally with the ring, extends outwardly from the inner end of each piston, and has a bight portion 63 adapted to receive at times the bight portion of the yoke 50. The yoke slides in the arms of the lever 62 which acts as a guide for the yoke. Tracks may be provided in the arms of the lever to receive corresponding ribs on the yoke.

As shown more particularly in Figure 1, the crank pin 53 is tapered at 70, and re ceived by a complementarily formedsocket "('1 in a flywheel 72. A nut 73 secures the tapered end of the pin to said wheel. A shaft 74, located axially of the flywheel has a tapered portion secured to the wheel.

A tube 80, which acts as a valve, is supported by means of a cap or flanged plate 81, and has its inner end conically shaped, as shown at 82, which is provided with a port 83 adapted to aline at times with a passage 84 formed in a trunnion 18. A lug 85, secured to a plate 86, is adapted to project through a passage 87 in the tube for preventing rotation of said tube. An inlet pipe 88 is connected with a tube 80, and is adapted to supply the said tube wit-h liquid fuel under pressure. A spring 89 carried by the flanged plate 81 maintains a conically shaped end 82 and the tube 80 against its socket. As the cylinder oscillates, it will automatically place the passage 84; in communication with the port 83 at times when the engine has been designed for supplying the combustion chamber of the engine with a predetermined quantity of fuel.

A hexagonal portion 56 of the rod 56 is provided at a pointon the rod for engagement with a suitable tool for rotating the said rod and adjusting the same lengthwise of the yoke 50 when it is desired to place greater pressure on the block 5& to maintain the bearing 55 in position.
